Hey Zepp, For each photo you sell how much $ does the car owner get from you? The owner is the one who puts out the $ so the car can get to the track so you can take the picture so you can MAKE $$. I know a top 410 car owner that puts reflective #'s on his car so photographers can't make money off of him.
If I was a car owner I'd be talking to that guys sponsor and tell them I won't restrict there exposure buy keeping images of the car out of publications and the internet. Talk about diminishing return on investment for the sponsor.
